  • Installation Costs: Including downtime and labor, let’s estimate $500,000.
  • Total Initial Investment: $2,500,000.

Operating With ESS:

  • Fuel Savings: The ESS improves efficiency and reduces the ship’s diesel consumption by 15%.
  • New Daily Fuel Cost: 20,000 liters x (1 – 0.15) x $1.00/liter = $17,000/day.
  • Annual Fuel Cost with ESS: $17,000/day x 250 operating days/year = $4,250,000/year.
  • Annual Fuel Savings: $5,000,000 – $4,250,000 = $750,000/year.

Additional Savings:

  • Maintenance Cost Reduction: Due to less wear and tear on the main engine, let’s estimate a 10% reduction in annual maintenance costs.
  • Initial Annual Maintenance Cost: $300,000/year.
  • New Annual Maintenance Cost: $300,000 x (1 – 0.10) = $270,000/year.
  • Annual Maintenance Savings: $300,000 – $270,000 = $30,000/year.

Payback Period:

  • Total Annual Savings: $750,000 (fuel) + $30,000 (maintenance) = $780,000/year.
  • Payback Period: $2,500,000 (initial investment) / $780,000 (annual savings) ≈ 3.2 years.

Long-term Benefits:

After the payback period, the ship continues to save on operational costs, amounting to significant savings over the lifespan of the ESS. In addition, the ship may benefit from improved market positioning by meeting green shipping standards and possibly earning carbon credits or qualifying for environmental incentives.
